Crankshaft Position Sensor A Circuit

This means the vehicle s ecm electronic control module has not yet detected the crankshaft position sensor during the first second of cranking of the engine.

Crankshaft position sensor a circuit.

The crankshaft position sensor is a stationary piece but it works with the reluctor ring to determine positioning and voltage. The pcm uses the crankshaft position sensor and the camshaft position sensor to vary fuel mapping and timing. Measure the ohmic values inside the crankshaft position sensor with a multimeter. If you get no results that means there is an open circuit inside the sensor.

The crankshaft position sensor ckp measures crankshaft location and relays this information to the pcm powertrain control module. Replace the crankshaft position sensor. This information is used by the electronic control module ecm to control ignition and fuel injection. Error code p0335 is described as crankshaft position sensor a circuit malfunction.

The crankshaft position sensor ckp also known as the crank position sensor is an electronic device used in an engine to record the rate at which the crankshaft is spinning. Depending on the vehicle the pcm uses this crankshaft position information to time the spark properly or on some systems it is only for misfire detection and does not control spark timing. An advanced level scan tool is an important diagnostic tool for p0335. The crankshaft position sensor is used to monitor how fast the crankshaft is spinning.

The computer reads this in rpm s.
